The syscall pages are written to be used also as man-pages. However, they don't match the format used by kernel-doc generated pages from DocBook. Rewrite them to match it. One side effect is that now all such pages at the book will have the same format, reducing the format differences between DVB and the other parts of the book.

DESCRIPTION
|
|
-----------
|
|
|
|
This ioctl is obsolete. Do not use in new drivers. For V4L2 decoders
|
|
this ioctl has been replaced by the
|
|
:ref:`VIDIOC_TRY_DECODER_CMD <VIDIOC_DECODER_CMD>` ioctl.
|
|
|
|
This ioctl tries a decoder command. The ``video_command`` struct is a
|
|
subset of the ``v4l2_decoder_cmd`` struct, so refer to the
|
|
:ref:`VIDIOC_TRY_DECODER_CMD <VIDIOC_DECODER_CMD>` documentation
|
|
for more information.
|
|
|
|
|
|
RETURN VALUE
|
|
------------
|
|
|
|
On success 0 is returned, on error -1 and the ``errno`` variable is set
|
|
appropriately. The generic error codes are described at the
|
|
:ref:`Generic Error Codes <gen-errors>` chapter.
